This video tutorial from Hank Ottey does an excellent job of explaining RF and Antenna Basics as they apply to 802.11 wireless systems.
The tutorial covers two broad areas:
Aspects of Antennas (gain and signal speed; reciprocity; range; and mounting).
Enemies of Signal Quality (multipath; obstructions; Fresnel Zones; and weather).
Each section is well-illustrated with graphs, photos, and other data.
